Abstract

A device for a detecting a hot box condition on a rail vehicle comprising a housing removably coupled to an undercarriage component of the rail vehicle, the housing being coupled magnetically; and a temperature sensor positioned within the housing.

Claims

1. A device for detecting a hot box condition on a rail vehicle, comprising:

a housing removably coupled to an undercarriage component of the rail vehicle, the housing being coupled magnetically; and

a temperature sensor positioned within the housing.

2. A device as set forth in claim 1, wherein the undercarriage component is a rotating component.

3. A device as set forth in claim 2, wherein the undercarriage component is a wheel.

4. A device as set forth in claim 2, wherein the undercarriage component is an axle.

5. A device as set forth in claim 2, wherein the temperature sensor is powered through rotational acceleration force.

6. A device as set forth in claim 2, wherein the temperature sensor is powered through a battery.

7. A method for retrofitting a rail vehicle for detecting a hot box condition, comprising the step of:

removably coupling a housing of a hot box condition detector to an undercarriage component of the rail vehicle, wherein the housing is coupled magnetically and a temperature sensor is positioned within the housing.

8. A method as set forth in claim 7, wherein the temperature sensor is powered through rotational acceleration.
